Rollup merge of #132123 - lolbinarycat:rustdoc-search-foreign-func, r=notriddle

Browse Source 
allow type-based search on foreign functions

fixes https://github.com/rust-lang/rust/issues/131804

preferably will be merged after #129708, but that may take a while to be approved due to being a new feature, whereas this is definitely a bug, and should be fixed.
